[0002] In neurotherapy, electrical stimulation is an effective treatment option that regulates dysfunctional neural activity by electrically stimulating specific nerves. General neurostimulation treatment equipment includes a stimulator and electrodes. The stimulator uses electrodes that are in direct contact with the patient to diagnose and treat the patient's nerve-related problems using electrical stimulation.

[0003] A general neuromuscular stimulation system includes a host that outputs electrical stimulation and electrodes that transmit electrical stimulation. At present, electrodes are still universal electrodes on the market, and there are the following problems in terms of medical safety and effectiveness: the electrodes used for each special treatment with the stimulator are different in terms of application scope, main technical parameters, connection methods and usage methods, and the use of inappropriate electrodes may lead to reduced effectiveness and safety issues. Certain relevant characteristics of the electrode may change over time, or cause some medical and health related problems due to repeated use, so its service life should be considered, including the effective time or number of uses.

[0004] In the prior art, there is a method of identifying an electrode sheet with a dedicated connector, such as patent CN215741368U. Although this method is highly specific, it is not conducive to the application of a large number of different types of electrode sheets.

[0005] At present, radio frequency identification (RFID) technology has been widely used in various industries. The general RFID system includes RFID tags, RFID readers, and communication antennas. RFID readers can provide energy or information to RFID tags and receive information from tags. RFID tags are usually fixed on objects to provide specific identification information.

[0010] Furthermore, the chip is provided with an EEPROM memory for storing identification codes, the number of times the electrode sheet is used, and the effective time of the electrode sheet. The identification code set in the EEPROM memory is used by the RFID card reader to identify and determine whether it corresponds.

[0011] Furthermore, the loop antenna is connected to the chip and is located at the same level. The RFID tag receives the radio frequency signal of the RFID reader through the loop antenna and sends its own stored information to the RFID reader.

[0012] Furthermore, the label surface material and the label base material are made of PET, and the loop antenna and the peripheral antenna are made of metal.

[0013] Furthermore, the electrode sheet 3 includes a connected connector, a wire and an electrode patch, and the RFID tag is fixed on the wire and is 2 cm away from the connector.
